Where Jev makes a decision
Jev evaluates the assembled tool descriptors against agent state using OpenRouter decisions API, returning high-confidence tool selection or fallback.
What this project offers
Separates tool routing from problem solving, eliminating wasted LLM tokens and latency across large, overlapping MCP tool registries.
Review scope
Author and repository text is preserved where clear; missing languages are enriched automatically. Checks establish source-level Jev integration, not runtime, safety, or performance validation.
